My invention relates to the class of machines that are commonly employedfor stamping, punching, dieing or other similar operations, and anobject of .my invention, among others, is the production of a machine ofthis class of simple construction, that will prevent undue wear upon thedies and that'will be otherwise particularly efficient in operation. 7

One form of a machine embodying my invention and in the construction anduse of which the objects herein set out, as well as others, 'may beattained, is illustrated in the accompanying drawings, in which Figure 1is a view of my improved machine in front elevation, with parts brokenaway to show construction.

Figure 2 is a view in vertical section through the driving shaft on aplane denoted by the dotted line 2-2 of Figure 1, the machine framebeing shown in side elevation and with parts broken away to showconstruction.

. Figure 3 is a view in cross section on a flp1ane denoted by the dottedline33 of Figure 1'; I

Figure 4 is a view, partially in plan and partially in cross section, ona plane denoted .by the dotted line el-1 of Figure 1. Figure 5 is a faceview, scale reduced, of

frame.

lgure 6 1s a view, scale reduced, of the main or supporting frame of themachine.

My improved machine belongs to that type of presses in which theoperating mechanism is located within the main supporting part of theframe and below the .bed or table that carries the stationary .die,

and in which a reciprocating die or punch is carried by a head locatedabove the table or bed and forming part of a sliding frame, said framebeing operatively connected with the operating mechanism forreciprocating movement thereby.

' In the accompanying eral l0 denotes the main or supporting frame of myimproved machine having a broad base for stable support ofsaid frame andwith a chamber 11 within the frame, a

table ,or bed. 12 for supportof a stationary die forming thetop ofrsaidchamber. Vertically extended ribs 13 and 14 are oppositely arranged 011the outer and inner sides of the side parts of the mainframe, and asshown in Figure 3 of the drawings, and bearings are suitably formedwithin the sides thus thickened to receive a main or driving shaft 15which is rotatably mounted in said bearings and which may be driven inany suitable manner, as by means of a driving pulley 16. This pulley isrotatably mounted on the shaft and is adapted to be intermittentlyconnected therewith by means of a suitable clutch that may be of anywell known construction and that may be ioperated in, any wellknOWn-xmanner, as will be readily understood by those skilled in theart, and for this reason a detailed illustration and description areomitted herein. A suggestion, however, of this clutch is shown in Figure2 wherein a notch 17 in I the main shaft receives a pawl 18for'connecting the pulley andshaft when desired. Openings are formedthrough the front and rear sides of the main frame for access to themechanism therein, and wide slots 19 are main frame fora purpose to behereinafter The upper or movable die iscarried by a. sliding 7 framecomprising side members 7 20, a reciprocating head 21 vand a tiebeam 22.The side members are arrangedtoxslide on the outer surfaces of the sidesofthe mainframe, as upon ways 9 at opposite sides of said frame, and thetiebeam 22 is secured at itsends, as by bolting or otherwise, to, theinner sides of the sliding members, extending through the s1ots 19,vsaidbeam beingof a-length to space said side members a proper distanceaparthThe side members may be cut or slotted at then upper ends to formextensions 23, and studsQL are formed, at the-ends'ofthe extensions 23to, drawings the nuns receive the head 21, inv the construction hereinshown said head having holes to receive the'studsf'and the latterbeingthreaded l .to receive nuts to'se'cuie the parts-firmly together.The WaysQYa'ifOrd extremely long lateral movement and so substantiallypre vent wear of the dies fromsuch cause. T he ribs 14i on the mainframe project into grooves 25 on the inner surfaces of the side members20 to act as guides for e members. Tapered gibs 26 may be lllSQltQCl'between the side members 20 and the-guide ribs 14 as a means for takingup wear. Guides 27 having lips overlapping the side members 20 to holdthem against the frame are secured to the sidesof the main frame andform grooves within which the side members move vertically when inoperation;

Reciprocating movement is ii'nparted to the sliding frame, and hence to.the movable die, by means of a toggle connection, in ii e specificstructure herein shown the tie beam 22 having a pillow block 28 on itsupper side .witha recess 29 in said block, the edges of opposite sidesof said recess having bearing notches that receive a pin 30 extendingfrom oppositesides of a link 31 comprising one member of said toggleconnection. This link is pivotally attachedto one 6110. of a lever32having a slot 33 that receives an ac- I outer end ofthe lever 32 has apin 36seated in bearing notches in the edgesof opposite tuating block 34mounted forreciprocating movement in said slot. Said -blocklsengaged'with acrank 35 formed on-tlie driving shaft 15 within thechambei'll. The

sides of a recc'ss 37 in a thrust block 38secured to the under side ofthe bed or table;

.12 and as shown-in Figure '2 (if the drawings. This constructionprovides for the application of lateral force to the side mem bers ofthe sliding frame to a minimum degree and thereby reduces relativelateral "force, to negligible quantity.

Sp,rings 3.91am seated in recesses in the bottom of the chamber 11, saidsprings being located on opposite sides of the'be'am and thrusting attheir upper ends against "overhanging lips s0 projecting from oppositesides of. said beam and as shown in dotted lines in Figure 2 ofthedrawings. It will be noted that the constant pressure .of the springs 39not only maintains the pins 30' and 36 seated in their bearings, but

further, that said springs act to lift the slid f ing frame and themovabledie under con trol of the lever 32 and the actuating block .34.The tension of these springs ispref erably such as to; counterbalancethe weight or the sliding frame so that substantially the same forcewill be required to move said' frame in both directions vertically.

It may further be noted that by the larrangement Of 'bl16 mechanism forimparting reciprocating movement to the sliding frame I obtain two.complete reciprocating 'movements thereof, and hence ofthe dies, in eachrotation of the crank shaft, and this is a material feature'of myinvention, asthe speed of operation of the machine may be hereiiiabovcdescribed with the exception that'tho'toggle members 41 and IQ-aresubstantially of the same length. A crank rod 18 isfattached to the kneeoint of the toggle -members at oneend and its opposite end is attachedto a crank pin pro ectmg from a crank disc 44 secured to the shaft 15. V

In accordance with the provisions of the patent statutes I havedescribed the prii ciples of operation of my. invention, together withthe device which I now consider to represent the best embodimentthereof; but I desire to have it understood that-the device shown isonly illustrative, and that the iiivention may be carried out by othermeans and applied to. uses other thanvthose a'bove set out.
